Ratings and reviews


Beyerdynamic MMX 300 2nd Generation Premium Gaming Headset SKU: MMX300-2GEN

Rated 5 out of 5 by from Exactly what you would expect from Beyerdynamic I own a pair of Sennheiser 660s's and pc38x for gaming. Had a baby and needed to switch to close back configuration. These phones check all the boxes in RPG and FPS games. mids are a slightly cloudy but high end and low end are bright and punchy respectively. Would definitely recommend to someone looking for superior sound quality with a mic.

Rated 5 out of 5 by from Great headphones Headphones sound great out of the box but go to another level with the Dekoni Choice Leather earpads. Build quality is typical Beyerdynamic (Very good) and the sound signature is similar to the DT770 with better tuning for games.

Rated 5 out of 5 by from Awesome - as expected These headphones sound amazing and I can wear them for hours with no discomfort. The sound from the mic is crystal clear. Exactly what I wanted!

Rated 5 out of 5 by from Great quality mic and superb sound I bought this headset a few weeks ago from Focus Camera through Google Shopping and I am very glad I pulled the trigger on this headset. The sound quality from the 2 channel drivers is second to none that I have owned in the past. I can't say I've had many $300+ headsets but I can say that of those, this one wins hands down in every category, including comfort. Which can be improved if you want to by purchasing different ear cups (which I learned are fairly standard sizes), so the options are out there if you need more plush ear pads. I have read reviews where they say the mid range is the only bit of this headset that can feel a bit far back on the sound stage, and I do see this in my own experiences but I find it takes nothing away from vocal performances. The bass is everything I need and more with excellent lows and highs so I do not feel you really need more at least when wearing a headset. I will leave the room shaking bass to my dedicated stereo system. As for the microphone, it is very sensitive and really stands out when you mess with gain and overall volume settings. I look forward to pairing this with a GOXLR sometime in the future to get even more out of the mic. But given the limited windows audio settings you can still get amazing clarity and tone from the boom mic. I am definitely considering one of Beyerdynamic's XLR headsets in the future because this mic seems to be the best I've used on a gaming headset so I can only imagine how much better a proper XLR setup could be. One potential flaw I see is the fact that they decided to use a proprietary cable to connect the headset to a PC or mobile device which means if you need a replacement out of warranty, you need to contact the Beyerdynamic USA store directly and ask them for a part order form that you have to fill out to get a replacement cable. They do not sell them directly on their website due to a limited quantity. So keep this in mind if you tend to be hard on your headsets because eventually you may need to replace the cable or manually rewire. To sum up, the headset is high quality and not a gaudy design which I appreciate. So if you have the money it is well worth it and I do not really see anything wearing out quickly. And everything can be replaced with a spare part, just the cables are the hardest bit to get.
